Overview

E340 - Potassium phosphates

Potassium phosphates (E340) are the potassium salts of phosphoric acid used to control acidity, stabilize proteins, and help ingredients mix smoothly. They show up in drinks, dairy alternatives, processed meats, and many powdered or instant foods. People with kidney disease may need to limit phosphate additives, but they are widely approved when used as intended.

E452 - Polyphosphates

Polyphosphates (E452) are a family of phosphate salts used in foods to hold water, stabilize texture, and keep minerals from causing off-flavors or haze. They appear in processed meats, seafood, dairy, and some beverages, and are regulated for safety and use levels in the U.S. and the EU. They’re part of the broader phosphate group that includes phosphoric acid and phosphate salts.

Popular questions

Is potassium phosphate bad for you?
Potassium phosphates (E340) are approved food additives and considered safe at typical dietary levels; EFSA set a group ADI for phosphates of 40 mg phosphorus/kg body weight per day. People with kidney disease or on potassium/phosphate-restricted diets should limit them.
How much potassium is in 15 mmol of potassium phosphate?
It depends on the salt: 15 mmol KH2PO4 provides 15 mmol K ≈ 587 mg; 15 mmol K2HPO4 provides 30 mmol K ≈ 1,174 mg; 15 mmol K3PO4 provides 45 mmol K ≈ 1,760 mg.
What is mono potassium phosphate?
Monopotassium phosphate (MKP, KH2PO4) is the monobasic potassium salt of phosphoric acid, designated E340(i). In foods it’s used mainly as a buffering/acidity regulator, stabilizer, and nutrient source.
What is potassium phosphate used for?
As food additives (E340), potassium phosphates function as buffering agents/acidity regulators, emulsifying salts, sequestrants, stabilisers/thickeners, and humectants. They’re common in processed cheese, dairy, meat products, and beverages to control pH, improve texture, and supply potassium.
How to install eufy doorbell e340?
That’s unrelated to the food additive E340 (potassium phosphates). Please check Eufy’s product manual or support for installation instructions.
